The blunder check
This lesson uses chess positions. Until you have played a little, its board questions are worked examples to read. New to chess? Play your first moves (five minutes), then learn it from the beginning.
In chess the blunder check becomes a habit because you run it every move. Off the board it becomes one only if you practise it there too, as this week’s task asks.
